Track everything you read, watch, and listen to. Drag your sources into Claude, ChatGPT, Gemini, or Grok and quiz yourself — the single most effective way to actually remember it.
Free. Works with your existing AI subscription. macOS 14+
Add anything you learn from. FeynmanLM keeps it all in one library in your iCloud.
Find what you need across all your sources instantly.
Drag sources straight into Claude, ChatGPT, Gemini, or Grok. Use the subscription you already pay for — no extra costs. Also supports MCP for a persistent connection to your full library.
Research is clear: quizzing yourself is the single most effective way to learn. Not re-reading, not highlighting, not summarizing. The AI tests your understanding, probes gaps, and saves your sessions. (Andrej Karpathy on this)
Work with your past learning sessions to find connections between sources, surface new ideas, and revisit what you've learned before you forget it.
FeynmanLM is not a note-taking app. There are plenty of those. It's a source tracker and learning tool. You bring the content, AI brings the quizzing. Read more about our approach →
